[ct] Cleanup after timetrap timeout or kill during framework call or hook

If a framework callback function exits due to a timetrap timeout, or
the process in other way is killed, during the execution of such
function, some internal common_test data was not cleaned up. An
example of such data is the 'curr_tc' test data. This is now corrected.
